PLOW.

SPECIFICATION forming part of Letters Patent No. 7o3,571, dated July 1,1902. Application filed August '7, 1901I Serial N0.7 1,129. (No model.)

T to whom it mag concern.-

Be it known that I, ALFRED K. GOODBIOH, a. citizen of the United States,residing in the city and county'of San Francisco, State ofCalifornia,have invented certain new and useful Improvements in Flows;and I dohereby declare the following to be a full, clear,-and exactdescription of the same.

The present invention relates to improve ments in plows for use inconnection with the work of cutting and turning a furrow and looseningthe subsoil below the main furrow, the object of the invention being theproduction of an improved combined subsoil and surface plow.

To comprehend the invention, reference should be had to the accompanyingsheet of drawing.

In the drawing the letter A is used to indicate an ordinary plow-standard, A the draft-beam, and A the plow-handles, which handles areconnected at the upper portion to the beam A by braces B. To the lowerend of the standard A is attached the share B, from which extends thewing 13*. The wing and share constitute the subsoil-share for the plow,the function of which is to loosen the soil at a depth below the furrowproper. Owing to the shape of the said share, the soil is only loosenedor broken and not turned over, as is usual with the surface-plow. Aslight distance above thesubsoil-share is arranged the share 0, to whichis attached the moldboard O. The moldboard C and share 0 constitute thesurface-share of the plow, in contradistinction to the subsoil share. Asarranged a space a exists between moldboard 0 and the wing B of thesubsoil-share.

The'moldboa'rd C is of the usual shape, and its purposeis to'turn overthe furrow cut by the share during travel of the plow.

By the employment of the hereinbefore-described plow the subsoil isloosened and the main'furrow cut and turned at one operation, theexpense of second plowing being thus avoided.

The space left between the shares serves to separate the cut layers andprevents the surface-share turning the subsoil layer with the main orsurface furrow.

Having thus described the invention, what is claimed as new,- anddesired to be protected by Letters Patent, is

In a plow, the combination with a goosenecked beam A and standard Acontinuous from end to end, a subsoil-share B secured to the lower endof the standard, a wing B carried by said share, a surface-share Osecured to said standard near the upper portion thereof so as to leave aspace between the same and said first-mentioned share, a moldboard 0carried by said surface-share, separated operating-handles projectingrearwardly from said shares, and braces B, B, one between each handleand the rear portion of the beam A; substantially as described.

In testimony whereof I have hereunto affixed my signature, in thepresence ofrwitnesses, in the city and county'of San Fran cisco, Stateof California, this th day of July, 1901. i
